SAFETY-RAZOR.

Specification of Letters Patent.

Patented Feb. 5, 1907.

Application filed February 24.1906. Serial No. 302,697.

To all 11171.07) it nmy concern: I

Be it known that I, ALoNzo A. WARNER, a citizen of the United States, residing at New ritain, county of Hartford, Connecticut, have invented certain new and useful Improvements in Safety-Razors, of which the following is a full, tion.

My invention relates to improvements in shaving appliances, and particularly to safety razors, so called.

The object of the invention is to provide simple and effective means whereby the cutting edge of the blade or blades may be adjusted relatively to the guard portion. The construction comprises but few parts, all of which are easily assembled for use or separated for cleaning.

In the drawings, Fi ure 1 is a side elevation of the razor, all parts eing assembled. Fig. 2 is a view of the under side thereof. Fig. 3 is a view of the under side with the bottom member detached and removed. Fig. 4 is a view of the under side of the handle and guard member, all of the other parts being detached. Fig. 5 is a plan view of the adjusting device. Fig. (3 is a planview of the blades. Fig. 7 is an end elevation of the end device as shown in Fig. 1. Fig. 8 is a view of the top side of the bottom plate. Fig. 9 is an end elevation thereof.

1 is the handle, formed of any suitable materialsiu:h as hard wood, rubber, or ivory.

2 is what I. will term the guard member or backing member. This part is preferably formed integrally of the handle 1 and may be of the same material. N otches are cut in this backing member 2 to form the individual guard members or tongues 3 3. j

1 is a central passage through the backing member 2.

5 is an abutment on the backing member 2. This abutment stands above the surface of said member and extends tively thereto. As best seen in the guard or backing member has a longitudinal cavity or recess'in its lower side to receive a blade-adjusting member 6. This adjusting member has an elongated opening or recess 7 to afl'ord clearance for the abutment 5, and this opening is of such length as to permit the adjusting member 6 transversely rela- Figs. 4 and 7,

I tended slightly, as at 7, to afford clearance clear, and exact descrip.

being of sutlicient size to for the central screwstump later described.

8 8 and 8 8 are guide-pins on the adjusting member 6.

9 and 9 are blades, and these blades are supported on the adjuster 6 and the adjacent edges of the guard or backing member 2. These blades areprovided with cam-grooves 10 10 and 10 10*, respectively. These grooves 10 10 and 10 10 are adapted,respectively, to the guide-pins 8 8 and 8 8, respectively.

11 11 are notches formed in the opposite inner edges of said blades 9 9, said notches afford clearance of the abutment 5. The width of each of said notches is, however, only very slightly greater than the width of said abutment, so that the blades cannot be shifted longitudinally relatively to the backing 2.

As shown in Fig. 3, the blades stand in an intermediate position of adjustment. If the adjusting member 6 is moved to the right, the action of the pins 8 8 8 8* will be to eX- pand the blades and push the cutting edge outwardly relatively to the guard-tongues 3.

If the adjusting member 6 is moved to the left, the action will be reversed, the blades 9 9* being drawn back or toward each other, exposing less of the edge for cutting purposes.

12 is the bottom lower side of which forms a smooth unbroken bearing or Contact surface for the face, while the upper surface of the same bears against the blades 9 9 and holds them tightly against their seats.

13 is a screw-stump carried by the plate 1 2 and passing through the perforation 4 1n guard member 2. A thumb-nut 14 on stump 13 affords means by which the parts may be clamped together when the proper adjustment of the blades has been effected.

- In the preferred form of construction the abutment 5 and length as to project entirely through the blades 9 9 and hence suitable clearance spaces or grooves 12 are desirable in the top side of the clamping-plate 12.

From the foregoing it will be seen that to adjust the blades itis merely necessary to let upslightly on'the thumb-nut 14, Whereto be shifted to upon the blades are freed sufliciently to perand fro. The clearance-passage 7 is also eX- 1 mit the adjusting or Clamping plate, the

the pins 8 8 are of such fro. By this movement the cutting edge of the blades will be projected to the desired degree. By again setting down the thumbnut 14 all the parts are rigidly clamped together.

What I claim is 1. In a safety-razor, a guard or backing relatively to said backing member, an adjusting device longitudinally movable relatively to said backing member, a guidepin carried by said adjusting device, a cam groove in said blade into which said guidepin projects, all arranged whereby when the adjusting member is moved longitudinally member, guard-tongues at opposite edges the. blade will be moved laterally to expose thereof, two independent blades providing more or less of its cutting edge, and means cutting edges adjacent to the guard members I for clamping said parts rigidly in any desired at each edge of the backing member, means position of adjustment. for moving simultaneously said blades to- 3. In a safety-razor, a handle having a Ward or away from each other for causing backing portion with guard-teeth arranged said cutting edges to project more or less, as 1 along opposite edges and disposed on oppodesired, relatively to the guard-edges, said site sides of the longitudinal axis of the means consisting of an adjusting member j handle, and alongitudinal positioned between the guard member and 1 ing member located in said groove, and clamping-plate and provided with-a series of means for clamping a blade to the backing pins engaging in slots in each of said blades. 1 portion.
